Rhubarb Dream Bars Ingredients
• Here’s everything you need for making these delightful bars!
For the Crust
- All-Purpose Flour – Provides structure for the crust and filling; for a gluten-free version, use a 1:1 gluten-free flour blend.
- Powdered Sugar – Adds sweetness and a delicate texture to the buttery crust.
- Butter (cold and cubed) – Infuses richness and ensures a flaky, tender crust.
For the Filling
- Large Eggs – Acts as a binding agent, essential for the creamy, custard-like texture. Note: Room temperature eggs mix better for an even consistency.
- Granulated Sugar – Sweetens the filling and balances the tartness of the rhubarb.
- Salt – Enhances the overall flavor of the Rhubarb Dream Bars.

Step‑by‑Step Instructions for Rhubarb Dream Bars
Step 1: Preheat and Prepare
Begin by preheating your oven to 325°F (163°C). While the oven warms up, grease a 9×13 inch baking pan to ensure your Rhubarb Dream Bars release easily after baking. This preparation is crucial, so don’t skip this step, as it creates a lovely foundation for your dessert!
Step 2: Make the Crust
In a large mixing bowl, combine 2 cups of all-purpose flour with ½ cup of powdered sugar. Next, cut in 1 cup of cold, cubed butter using a pastry cutter or your fingers until the mixture resembles coarse crumbs. This buttery crumb mixture will form the base of your Rhubarb Dream Bars, giving it a light, flaky crust.
Step 3: Bake the Crust
Evenly press the crumb mixture into the bottom of your prepared baking pan, creating a solid layer. Place the pan in the preheated oven and bake for 15 minutes, or until just set but not browned. This step creates a lovely foundation to support the tangy filling that follows.
Step 4: Prepare the Filling
While the crust is baking, whisk 4 large eggs in the same mixing bowl until lightly beaten. Stir in 2 cups of granulated sugar, followed by ½ cup of all-purpose flour, 1 teaspoon of salt, and cinnamon (if desired). This mixture will develop the custard-like filling of your Rhubarb Dream Bars, ensuring a delightful flavor balance.
Step 5: Add the Rhubarb
Carefully fold in 4 cups of diced rhubarb, making sure it’s evenly distributed throughout the mixture. The vibrant chunks of rhubarb will provide that signature tangy flavor that defines your Rhubarb Dream Bars. Once evenly mixed, it’s time to pour the filling over the pre-baked crust.
Step 6: Bake the Bars
Return the pan to the oven and bake for an additional 60 minutes, until the center is set and no longer jiggly. You’ll know they’re ready when the top is lightly golden and firm to the touch. This final bake transforms the filling into a creamy, custard-like texture that perfectly complements the crust.
Step 7: Cool and Slice
Once done, remove the Rhubarb Dream Bars from the oven and allow them to cool completely in the pan. Cooling is essential—this helps achieve the perfect texture for slicing. Once cooled, cut into squares and serve to enjoy the delicious combination of flavors and textures!
